- Accuracy Guaranteed
- Results in 3 to 5 Days
- Easy to use Mouth Swabs
Overview – DNA Twin Testing
Knowing whether twins are identical or fraternal is difficult to base on appearance alone. DNA Twin testing aids in viewing with accuracy whether a set of twins are identical or fraternal. Identical twins are genetically identical and will share exactly the same DNA profile, whereas fraternal twins only share approximately 50% of their DNA in common.
A DNA sample is collected in the privacy of your own home using buccal swabs (mouth swabs) and sent to our laboratory for testing. The typical turnaround time for testing is 3 to 5 business days.
When testing is complete, you will receive a full laboratory report certifying the results of your DNA Twin Test.
How Does DNA Twin Testing Work?
The DNA twin testing kit contains four easy-to-use mouth swabs designed to painlessly collect a DNA sample from each individual for analysis. The mouth swab collected contains cells in which most of them contain a full set of genetic information in the form of DNA, short for deoxyribonucleic acid. An individual’s DNA acts as a “genetic blueprint”, and like a fingerprint, is unique between each person. Once the sample has reached the laboratory, the DNA is extracted from the cells and undergoes a process called PCR (polymerase chain reaction), which amplifies specific regions of the DNA. These amplified regions are carefully examined for a DNA pattern. The DNA patterns of the twins are then compared with each other. Based on the comparison performed, it can be conclusively viewed whether a set of twins are identical or fraternal.
Can the DNA Twin Testing Kit be Shipped to More than One Address if the Parties Live in Different Cities?
Yes. If the individuals to be tested live in different cities, or even different countries, the kit can be split and have each component sent to a different address. Since the kits are individually barcode labeled, they will be tested together once the samples arrive back at the laboratory. To order a split kit, please indicate which name and address to send each component. Alternatively, the entire kit can be sent to one address in which an individual of the party splits the kit and sends the other portion of the components to the other parties involved in the test.
How Long Does the DNA Twin Test Take?
The turnaround time for DNA Twin Testing is 3 to 5 business days from the date samples are received by our laboratory. The results of the twin test are provided immediately upon completion.
